- Draggable, collapsible to pulsing dot with session count
- Shows last 5 lines of most recent active session

- CSS styles using Mattermost theme variables
Phase 3: Session cleanup and KV optimization
- Add LastUpdateMs field to SessionData for staleness tracking
- Set LastUpdateMs on session create and update
- Add periodic cleanup goroutine (every 5 min)
